A Blizzard Warning is in effect until 1 p.m. Monday for McHenry and DeKalb counties in Illinois, where wind gusts of around 50 mph are likely until 6 a.m.

The blizzard warning until 1 p.m. also affects north central northwest, and western Illinois — including Rockford, Freeport, and Dixon. Another blizzard warning is in effect until 4 p.m. for most of Wisconsin, including Milwaukee and Madison. Kenosha County, Wisconsin, closest to the Chicago area, is also under a blizzard warning.

A Winter Weather Advisory is in effect until 1 p.m. Monday for Cook, Lake, DuPage, Kane, Kendall, LaSalle Grundy, and Will counties. A separate advisory is in effect for northern LaPorte County and parts farther east in northern Indiana and southwest Michigan.

In the immediate Chicago area, accumulations will be highest near the Wisconsin state line, between 4 and 6 inches there. For Chicago, 1 to 3 inches is possible.  

Chief Meteorologist Albert Ramon said that gusty winds will create blowing snow and reduced visibility to possible whiteout conditions. Blizzard-type conditions are possible at times in northwestern Cook and Lake County, IL, too, due to extreme winds.

The Department of Streets and Sanitation said crews will be out through Monday morning, monitoring arterial streets, DuSable Lake Shore Drive, bridges, and overpasses to keep roads clear for emergency vehicles, public transportation, and other travelers.  

What to expect during Monday's winter weather 

Monday Morning
The worst travel conditions are expected during the morning commute, especially northwest of Chicago.

As of 5 a.m., conditions on Chicago roadways were already extremely poor — especially in outlying areas. Little to no visibility was also reported in some areas.

On top of the snow, some streets and roadways were flooded from the rain that fell during storms Sunday night, and a glaze of ice was a concern in some areas. Side streets were covered in puddles of water in particular.

Blowing and drifting snow could continue to reduce visibility significantly and create slick roads. For Chicago, we're under a winter weather advisory for the threat of accumulating snow, slick travel, and reduced visibility. 

Monday Afternoon
Steadier snow should taper off, but scattered snow showers or brief squalls may still develop, which could lead to localized bursts of reduced visibility and slick travel.

Even though snowfall totals may not be extreme everywhere, the combination of accumulating snow and very strong winds will likely create the biggest impacts, especially overnight and during the Monday morning commute.

SkyWest Airlines flight 5783, operating as United Express, returned safely to O'Hare after the reported lightning strike, a spokesperson for SkyWest said.

There were no reported injuries.

The airline said they are working with customers to continue their travel to Portland as quickly as possible.

The risk for severe storms has left the area after 9 p.m., and all storm watches, warnings, and advisories have since expired.

The severe storm threat has prompted a ground stop at O'Hare Airport due to thunderstorms, according to the Federal Aviation Administration. A ground stop was also issued for Midway Airport. Flights have resumed with some delays.

The heavy downpours led to reports of flooded viaducts in Humboldt Park, New City, Portage Park, and Albany Park, with a submerged car at Garfield Park.

American Red Cross relocates Kankakee County shelter ahead of next round of storms

The American Red Cross has relocated its shelter for tornado victims in Kankakee County ahead of another round of storms.

Starting Sunday, the new shelter will be at Redemptive Life Ministries on Waldron Road. The shelter was to open at 3 p.m. on Sunday.

The organization is currently helping about a dozen people whose homes were damaged in Tuesday's storms. The shelter offers meals, charging stations, and help with government assistance. Pets in kennels are welcome.

Winter weather returns on Monday

A cold front crosses our area around midnight Sunday night. The Monday morning rush could be hazardous with blowing and drifting snow. Visibility could be near zero at times.

Snow amounts of 1" to 4" are possible, with 4" to 6" closer to Rockford. Areas that receive the most snow will have a likely chance for whiteout conditions at times.

A Blizzard Warning was issued from 10 p.m. Sunday to 1 p.m. Monday for McHenry and DeKalb counties in Illinois.

A Winter Weather Advisory will be in effect for Lake, McHenry, DuPage, Kane, Kendall, and LaSalle counties beginning at 10 p.m. Sunday and continuing until 1 p.m. Monday. Cook, Grundy, and Will counties will be under advisory from 1 a.m. to 1 p.m. on Monday. A separate advisory is in effect for northern LaPorte County and parts farther east in northern Indiana and southwest Michigan. 

Areas farther west have it worse.  A Winter Storm Warning has been issued for Boone, Lee, Ogle, and Winnebago counties, including Rockford, which is in effect on Sunday and will last until 1 p.m. Monday.

The National Weather Service warned of slick and hazardous roads during the snowfall.

The ages of the victims range from 16 to 63. 

Shootings from Friday

In the first shooting of the weekend, a 16-year-old boy was near the sidewalk in the 3700 block of West 60th Street around 7:14 p.m., when he was approached by at least one gunman who fired shots at him. 

The victim was hit in the leg and was taken to Christ Hospital in good condition.

Later in the evening, just before 9:30 p.m. in the 800 block of North Latrobe Avenue, a 39-year-old woman was parking her vehicle when another known woman approached her and began shooting at the victim before fleeing the scene. 

The victim suffered multiple graze wounds to the body and was transported to Mt. Sinai in good condition.     

Then, a little over an hour later, around 10:41 p.m., a man entered a convenience store in the 100 block of West Adams Street and began taking retail items from the shelf. The suspect exited the store and was confronted by a 31-year-old man. The suspect shot the victim multiple times before leaving the scene. 

The victim suffered multiple gunshots to the body and was taken to Northwestern Hospital in critical condition.

In other shootings from 5 p.m. Friday to 5 a.m. Monday:

Shootings from Saturday

Check back throughout the weekend for updates.     

Mr. Trump blamed the "radical left" in a social media post Saturday for refusing "to honor the deal that was approved and voted on in Congress." He directed portions of the post to TSA agents and said, "Keep fighting for the USA. GO TO WORK! I promise that I will never forget you!!! 

His post comes hours after the first full missed paycheck for TSA agents was expected Friday.

Roughly 50,000 transportation security officers are required to work without pay during the Department of Homeland Security funding lapse, which began on February 14. CBS News reported unscheduled absences among airport security officers have more than doubled since then, with more than 300 employees leaving the agency.

DHS officials worry that the longer the shutdown lasts, the greater the risk that more TSA employees will leave, worsening staffing shortages beyond the immediate crisis. 

"Our kids, our families, houses — everything is at stake at this moment," one officer told CBS News Atlanta. "We are literally drowning in silence, and the world doesn't even know it."

The CEOs of several major airlines, including American, Delta and United, sent an open letter to Congress on Sunday, writing that the missed paychecks are "simply unacceptable. It's difficult, if not impossible, to put food on the table, put gas in the car and pay rent when you are not getting paid."

The CEOs called on Congress to fund the Department of Homeland Security and pass the Aviation Funding Solvency Act, the Aviation Funding Stability Act and the Keep America Flying Act, which would guarantee air traffic controllers and TSA officers continue receiving paychecks in the case of another shutdown.

Dozens of airports around the country have reported long lines at security. The TSA temporarily closed one security checkpoint at Philadelphia International Airport on Thursday. There were long lines reported at Houston Hobby and New Orleans airports last weekend. 

In some cases, the strain has led to frustrations: Federal prosecutors charged a California man who allegedly became violent earlier in the week at Dallas Love Field airport. 

Idress Vinay Solomon, 33, of Oakland, is accused of assaulting a federal officer, according to the U.S. Attorney's Office for the Northern District of Texas. Solomon allegedly punched TSA and Dallas police officers after failing an identity check at the security checkpoint.

"Violent conduct perpetrated against TSA and law enforcement officers will never be tolerated in the Northern District of Texas," said U.S. Attorney Ryan Raybould.  "We will prosecute such offenses to the fullest extent to seek justice for the victims here and to deter others from resorting to aggressive attacks against officers responsible for ensuring the public's safety while traveling." 

A spokesperson for CTA said around 8 p.m., the operator of a northbound Brown Line train requested emergency responders due to a reported disturbance on board the train. 

According to the Chicago police, a woman was in a fight with two other women, 23 and 43, while on the platform. The suspect and the victims boarded the same train, where another altercation ensued, during which the two victims suffered cuts to their arms and hands. 

They were taken to Northwestern Hospital in good condition. The woman was later found and taken into custody.

Police did not say if any charges were pending.

Area 3 detectives are investigating.

At 10:40 p.m. Saturday, Joliet police were called to the 600 block of Wheeler Avenue for a report of a shooting, and learned that a car transporting a male gunshot victim had already left the area. The car was found at Meadow Avenue and Thorne Street in nearby Rockdale, Illinois.

Officers found a 15-year-old boy in the car who had been shot in the head. The driver of the car had flagged down a Will County Sheriff's deputy, who was providing emergency assistance, police said.

The victim was taken to St. Joseph Medical Center in Joliet in the deputy's car, with a Rockdale police officer assisting, Joliet police said. The teen was later transferred to Lurie Children's Hospital.

The teen was reported in critical condition.

A 14-year-old boy was also battered in the same incident, and was taken to St. Joseph Medical Center in an unspecified condition, police said.

Police believe the shooting happened at West Park. Officers canvassed the area for evidence.

Anyone with information on the shooting is asked to call the Joliet Police Department Investigation Division at 815-724-3020. Anonymous tips can be submitted to Will County Crime Stoppers at 800-323-6734 or online.

Illinois State Police said just after 3 a.m., a semi carrying 45,000 pounds of pet food rolled over on eastbound I-80 just past Harlem Avenue.

The left shoulder and two left lanes were blocked.

State police said the spilled pet food could take up to five hours to clean up.

It was not known Sunday morning what caused the semi to roll over.

Chicago police said the victim was found unresponsive on Thursday morning in the 11000 block of South Washtenaw Avenue in the West Morgan Park neighborhood.

Initially, police said the victim, whom the Cook County Medical Examiner's Office identified as Benilda Ruiz, 84, was pronounced dead at the scene, and that her death appeared to be due to natural causes. 

Examiners later determined that she suffered multiple injuries due to assault, and her death was ruled a homicide.

CBS News Chicago reached out to CPD for more information about the case, and they said they have reclassified the case as a Homicide with Area Two detectives investigating.

This comes as residents in the area are still cleaning up following Tuesday's severe storms.

"I'm just going to move the car back," said David Conway.

When Conway arrived at his Aroma park home on Sunday, he and his daughter, Laila Keske, came to get any necessities out of the house, and quick.

"I used to love tornadoes, and now I'm like 'look what it did,'" Keske said.

"I knew that the snow was coming, that was why I was trying to get a contractor so they can get on the roof and get tarps up," Conway said.

He said he and his three kids have lived in their home for the last seven years. It was destroyed by the tornado on Tuesday night and has suffered severe damage. They plan to put the important items in storage until they get word.

"It's like, where do I even start?" Conway said.

They aren't alone. The entire neighborhood is full of tarps, trees uprooted, and streets that look like a war zone.

While the community is trying to clean up, there's still the worry that it could all come tumbling back down.

All afternoon on Strasma North Drive, the constant sounds of chainsaws were heard in a last-ditch effort to get any hanging branches off trees. While many homes here are a total loss, some did not get hit, and those homeowners said they don't want any debris or trees hitting their homes from Sunday night's storms.

"We certainly know about it, and we are certainly concerned about it," Judy Giacomino, a volunteer with the Red Cross.

She and her partner went door to door on Sunday to assess the damage and help those in need. Giacomino said the people whose homes are still standing are dealing with mental stress that they could be next.

"I don't know what Mother Nature has in store, but she is certainly picking on Illinois right now," she said.

"I don't know about her over there, but I know Christy was saying she's going to stay," Conway said.

He said no matter what happens, his family plans to move back to the exact spot, new home or not, as they try to navigate this unfamiliar and uncertain situation.

The Red Cross did open a new shelter on Sunday afternoon at Redemptive Life Ministries on Waldron Road.

They said the last place they were at needed the space, but they are still here to serve anyone displaced.

A Frederick Wiseman documentary doesn't have a film score. There's no narration. No text identifying the people or places. No re-enactments. Not even interviews! They often depict meetings, phone calls, and conversations. And these movies are up to six hours long.

Not the ingredients you might expect for masterpieces. At a retrospective last year at New York's Film at Lincoln Center, one moviegoer, Ainsley, characterized the appeal of Wiseman's films this way: "He got out of the way and just let things happen as they are."

In 2016, Wiseman was awarded an honorary Oscar. In accepting his honor, he said, "It's as important to document kindness, civility, and generosity of spirit as it is to show cruelty, banality, and indifference."

Wiseman told us last year he didn't like the term "documentaries" very much: "No. I like 'movies' better. It's simpler. Maybe because when I grew up, documentaries were supposed to be good for you. And I thought what used to be called a documentary could be as funny, as sad, as tragic as a fiction film."

In his 96 years, he made 44 documentaries without ever telling you who's speaking, what you're seeing, or how to feel about it. "You have to answer it yourself," he said. "My job as an editor is to provide you with enough information in the context of the film so that you're stimulated to pose that question, and you can answer it yourself."

Wiseman grew up in Boston, and went to Williams College and Yale Law School. Then in 1966, he filmed an inside look at a state prison for the criminally insane. He called his movie "Titicut Follies." It caused a sensation — and changed his life.

He filmed prisoners – some half naked – and guards being pretty abusive. And no one told Wiseman to turn off the cameras. "No," he said. "Once they gave me permission, I had access to everything."

But "Titicut Follies" was so shocking, and politically embarrassing, that a Massachusetts court banned it.

Years passed. "And then in the mid-'80s, I saw an article that said, 'Titicut Follies Judge Dead.' I don't say that I was displeased with that news!" Wiseman laughed. "I brought a new action in front of a new judge. And ultimately it was cleared."

Wiseman's movies go behind the scenes of institutions: a high school, a hospital, a police department, a welfare office, a domestic-abuse shelter. Four of his early films Wiseman described as some of the most depressing films ever made. "There are aspects of some of the early movies that are depressing," he said. "There are also aspects that are extremely funny, in my view. I mean, if you have a sick sense of humor!"

For all his movies, Wiseman served as his own soundman. He also did no research before filming. "Shooting the movie is all chance," he said. "You never know what people are gonna say and do, which is one of the reasons I have to shoot a lot of film. And for most of films it's 100-150 hours."

Does the presence of a film crew subtly affect the way people behave? "Well, that's the eternal question," he said. "I don't think people are good enough actors to suddenly change their behavior."

After shooting those 150 hours of footage, Wiseman would spend eight to ten months alone in the editing room where, as he freely admitted, he shaped the story. "The notion that these movies are 'The Truth' is completely phony," he said. "It's one person's version. It's my version of a welfare center. Somebody else spending any time in a welfare center would make a completely different movie."

Over the years, Wiseman was occasionally asked to make a trim or two, and he always refused. He said, "It may be pretentious of me, but I think when I find a form for the material, that's the movie. They're not isolated sequences."

In 1971, "60 Minutes" wanted to air his film "Basic Training" – if he'd cut out 30 minutes to fit the time slot. "And I said no, because it wouldn't be the same movie," he said. "So, it wasn't shown."

What does he think his reputation is with these people? "I hope they'd say, 'He's a very nice guy, but he protects his movies,'" Wiseman said.

Wiseman's movies were never what you'd call theatrical blockbusters. They might play in 60 ot 70 theaters. But they did play on television. "PBS has shown everything," he said. "PBS has helped me in every single film I made."

But did they ever say, "Come on, Fred, six hours is too long for this one"? "Well, they said it once or twice, but I said, 'No.' And I won!" Wiseman said. 

Over the decades, his movies seemed to become more optimistic. For example, his 2020 movie "City Hall" showed how hard the staff of Boston's mayor worked to improve city life. But Wiseman wouldn't admit to any kind of shift – no trendline from darker to brighter. "It's totally random," he said. "When I'm looking for subjects, you know, it's a question of what interests me at the moment."

His last movie, "Menus-Plaisirs – Les Troisgros," about a fine-dining restaurant in the French countryside, came out in 2023. You can watch all of his movies, for free, on Kanopy.com; you just need a library card.

Meanwhile, they still teach Wiseman in film schools; they still put on Wiseman festivals; and when we visited his home in Cambridge, Massachusetts, his shelves were lined with awards.

"I mean, I obviously like the fact that the films were recognized, and that I get awards, or critics write intelligent reviews," he said. "But the satisfaction is not that; the satisfaction is the work. I love working. And I love making movies. And I never get tired of sitting in front of the editing machine."

Braden Smith had 14 points, 11 assists and three steals as Purdue (27-8) added to an impressive turnaround after closing the regular season with four losses in six games. Fletcher Loyer made three 3-pointers and finished with 14 points.

The Boilermakers won the Big Ten Tournament for the first time since 2023 and third time overall. They lost to the Wolverines in the final in 1998 and 2018.

Yaxel Lendeborg scored 20 points for top-seeded Michigan (31-3), which beat Purdue 91-80 in their regular-season meeting on Feb. 17. Aday Mara had 17 points, seven rebounds and two blocked shots.

Wearing No. 41 after his No. 3 jersey ripped early in the game, Smith helped the Boilermakers seize control by deftly running the pick and roll with Kaufman-Renn in the second half. The senior point guard has 1,075 career assists, just one shy of Bobby Hurley's NCAA record.

Two jumpers by Kaufman-Renn off passes from Smith powered Purdue to a 55-44 lead with 12:55 left. After Elliot Cadeau scored for Michigan, the 6-foot Smith drove inside, drew a foul on the 7-3 Mara and scored, drawing a big cheer from the Purdue fans in the crowd at the United Center.

Smith celebrated by pounding his chest as he walked toward a rollicking Purdue bench. He made the ensuing free throw for a 58-46 lead with 12:06 to go.

The Boilermakers made nine of their first 11 shots in the second half. They shot 15 for 26 in the second half overall.

Cadeau finished with 10 points and 10 assists for Michigan, which won the Big Ten tourney in 2025. Playing in his hometown, Nimari Burnett scored 12 points.

Purdue used a 12-2 run to take a 38-34 lead late in the first half. But Cadeau found Mara for an alley-oop dunk and converted a tying layup in the final seconds.

Up next

Michigan is likely headed for a No. 1 seed when the bracket for the NCAA Tournament is announced later Sunday.

Purdue is in the mix for a No. 2 seed after its impressive performance at the United Center.

The parade draws thousands of people each year to celebrate Irish heritage and community. It will step off at noon, filling Western Avenue with parade floats, marching bands, and thousands of people lining the streets for one of Chicago's best-known St. Patrick's Day traditions.

The parade was to run along Western Avenue from 103rd Street to 111th Street.

Floats staged along Western Avenue throughout the morning before the parade began, with more than 100 groups expected to take part in the parade.

The event features pipe bands, Irish dancers, community organizations, local schools, and first responder honor guards.

"We're very proud of this day. Our whole community, we work probably over half the year on it to organize it, and it's a great big gathering — you know, a lot of family parties," said South Side Irish St. Patrick's Day Parade executive committee member Pat Coakley. "You know, and again, you know, people kind of address each other a week or two before as like, 'Have a great parade day.' It's sort of a holiday."

This year's grand marshal is the Tunnel to Towers Foundation, a national nonprofit that supports the families of fallen first responders and military service members by providing mortgage-free homes and support services.

"We're thrilled. You know, our foundation is celebrating our 25th anniversary this year, and we have several families that we've been fortunate enough to help," said Aric Grooms of the Tunnel to Towers Foundation.

The name of the foundation honors Stephen Siller, the FDNY firefighter who on Sept. 11, 2001, abandoned his truck and ran through New York City's Brooklyn-Battery Tunnel with all his gear toward the World Trade Center. He was killed when the South Tower collapsed.

The foundation notably organizes the Stephen Siller Tunnel to Towers Run in New York, which draws tens of thousands of people in late September every year.

"Basically, our promise to the first responder and military community is this — if you have young children, and you kiss your kids goodbye in the morning, and you don't come back from your shift, we'll provide your family with a mortgage-free home," Grooms said.

Fr. Ryan Brady of St. Christina Parish in Mount Greenwood said the community was ready for the parade, even with wind and rain expected Sunday morning.

"We're hardy people down on the South Side, so we're happy, and we've been to this parade when it's been 70 degrees and sunny. We've been to this parade when it's been 5 degrees and snowing. But either way, what a great day to celebrate.

St. Christina is celebrating its 100th anniversary this year.

"We're so honored to celebrate who we are, who we were, and who we long to be," said Brady. 

Father Brady said the majority of St. Christina parishioners have been able to celebrate the South Side Irish Parade for their whole lives.

Chicago South Side Irish Parade organizers say the goal each year is to celebrate Irish heritage while keeping the event family-friendly and safe.

Organizers also remind people planning to come out Sunday to pay close attention to parking restrictions and street closures in the area as the parade route fills up.

The South Side Irish Parade began in 1979 as a brief march along two residential blocks by the "Wee Folks of Washtenaw and Talman."

The event went on hiatus after the 2009 parade, at which there were dozens of arrests, while local residents said the underage drinking and rowdiness had grown out of control. The parade returned in 2012, with a zero-tolerance rule for alcohol.

The parade was also canceled in 2020 and 2021 due to the COVID-19 pandemic.

Also Sunday, the Northwest Irish Parade stepped off at noon in the Norwood Park neighborhood. It starts at the Onahan School, 6634 W. Raven St., and then heading south to Northwest Highway and then northwest to Harlem Avenue.

The analysis showed the elder Khamenei was wary of his son, Ayatollah Mojtaba Khamenei, ever taking power because he was perceived as not very bright, and was viewed as unqualified to be leader, according to sources. 

The information gathered also indicated that the father was aware that his son had issues in his personal life, according to sources within the administration, the intelligence community and people close to the president.

Mojtaba Khamenei, 56, was selected to become Iran's supreme leader last weekend by the country's council of religious clerics after serving as a close aide to his father for years.

About eight days earlier, Ali Khamenei was killed in an Israeli missile strike in the opening salvo of the U.S. and Israel's war with Iran. 

Mojtaba Khamenei, who was believed to have been injured in that strike, has been reported to have remained in his father's inner's circle. 

Mr. Trump, Vice President JD Vance and other senior officials have been briefed on the intelligence about the younger Khamenei.

In private conversations, Mr. Trump has told people close to him that he doesn't know that the information conveyed to him about Mojtaba Khamenei matters. He thinks Iran is essentially leaderless right now, with the younger Khamenei possibly dead. 

The White House believes Iran's Islamic Revolutionary Guard Corps is calling the shots, a significant change from the theocratic dictatorship that has existed since the country's 1979 revolution. 

Spokespeople for the CIA, White House and vice president declined to comment. 

On Friday, Mr. Trump hinted publicly about Ali Khamenei's lack of faith in his son.

"Their leadership is gone. Their second leadership is gone. Now their third leadership is in trouble, and this is not somebody that the father even wanted," Mr. Trump told Fox News in an interview.

Mr. Trump has called the new supreme leader a "lightweight" who would be an "unacceptable" leader for Iran. He has also suggested he wanted some oversight over Iran's next leader.

The federal government on Friday offered up to $10 million for information on the location of Mojtaba Khamenei and nine other key Iranian officials.

Mojtaba Khamenei is Iran's third supreme leader since the 1979 Islamic Revolution, following his father and Ayatollah Ruhollah Khomeini. The succession from father to son is notable because the revolution overthrew a hereditary monarchy.

The U.S., now more than two weeks into the war with Iran, has been seeking to destroy the Iranian regime. Defense Secretary Pete Hegseth told reporters Friday that the younger Khamenei is "wounded and likely disfigured," and Vance said it was an apparent strike that left him wounded. His condition was not clear.

Since the U.S. and Israel's war with Iran began two weeks ago, more than a dozen attacks have been reported against oil tankers and other cargo ships in the Persian Gulf and the Arabian Sea. Iranian officials have openly threatened ships that pass through the Strait of Hormuz, a waterway that connects the Persian Gulf with the world's oceans.

Fearing attacks, oil tankers have all but stopped transiting the Strait of Hormuz, which carries around 20% of global oil — with mostly Iranian and Chinese ships making it through. And with nowhere to send their supply, some major Arab oil exporters have cut production. Over the last two weeks, oil prices have jumped around 40% amid worries about a supply crunch.

The disruption has led President Trump to consider offering naval escorts to ships passing through the Strait of Hormuz, in the hopes that military protection could clear up the gridlock.

"When the time comes, the U.S. Navy and its partners will escort tankers through the Strait if needed," the president told reporters Monday. "I hope it's not going to be needed, but if it's needed, we'll escort them right through."

But administration officials have suggested they aren't prepared to start carrying out naval escorts just yet. Energy Secretary Christopher Wright said this week "it'll happen relatively soon, but it can't happen now," and pointed to the end of the month as a possible timeline. 

Treasury Secretary Scott Bessent said escorts will begin "as soon as it is militarily possible."

Military experts tell CBS News that any effort to shepherd oil tankers through the Strait — past potential Iranian mines, missiles, drones and explosive-laden "kamikaze" boats — will require preparations to cut back Iran's ability to strike at targets at sea. After that, it could involve U.S. ships, jets and surveillance capabilities. But the operation would not be risk-free. 

What needs to happen for escorts to start?

CBS News military analyst Aaron MacLean described any possible mission to escort oil tankers as a two-phase operation: First, the U.S. needs to "prepare the battlefield by reducing the stockpiles that Iran has of anything that can kill ships," and then in a second phase, it could start carrying out escorts.

That first phase might already be underway, said MacLean, a Marine Corps veteran, former U.S. Naval Academy faculty member and former foreign policy adviser to GOP Sen. Tom Cotton of Arkansas.

Over the last two weeks, U.S. Central Command says it has struck around 6,000 Iranian targets, including anti-ship missile sites, drone manufacturing facilities and mine-laying ships.

Slashing Iran's military stockpiles — including its missiles, drones, mines and boats — is important before ships are escorted, MacLean said, because "you want the amount of incoming [fire] to be manageable enough that you can reliably intercept it when it happens."

"They could do it today, but the earlier you go, the riskier it is," MacLean explained. "If you put U.S. Navy ships in close proximity of the Iranian coastline right now, it's going to get real sporty real quick, and the risk is very high."

Seth Jones, president of the defense and security department at the Center for Strategic and International Studies, told CBS News the U.S. military is likely preparing for escorts in the Strait of Hormuz by "degrading the Iranian capabilities to lay mines and strike targets."

"I suspect the U.S. Navy is not going to want to enter that Strait unless it's pretty confident that the threats have been degraded, largely by the airstrikes," he said.

Asked when escorts could begin, Wright suggested on CNBC earlier this week that the Trump administration is still in the preparatory phase. 

"We're simply not ready. All of our military assets right now are focused on destroying Iran's offensive capabilities and the manufacturing industry that supplies their offensive capabilities," the energy secretary said.

How would escorting ships work?

The right time to start carrying out escorts in the Strait of Hormuz is a judgment call that U.S. Central Command would need to make, MacLean said. 

"You can't wait indefinitely because you've got to get that thing open," he said. "So at some point they're going to determine that they're comfortable with the risk, and then they're going to execute the convoy ops."

He said an escort operation could involve the Navy setting up staging areas where commercial ships are guarded at either end of the contested area — which may be constrained to just the Strait of Hormuz, or could stretch further into the Persian Gulf.

"And then, like a mother duck with her little baby ducks, a U.S. Navy ship, or a ship from a partner navy, is going to escort several ships through at a time," he said.

Those ships are likely to be supported by air cover and surveillance, added MacLean. And Jones said the mission could involve mine-sweeping capabilities, airstrikes on Iranian threats on the coasts and a nearby quick reaction force that can deal with attacks.

The first few ships to pass through might be targeted, said MacLean.

"We know the Iranians are going to shoot. We're looking to see where they shoot from, and then we hit them once they reveal themselves," he said.

Bessent said in an interview earlier this week that the escort operation could involve not just the U.S. Navy, but also an "international coalition." According to MacLean, potential participants may include developed countries like France, where President Emmanuel Macron has said the country's navy is considering a "purely defensive" mission to escort ships.

What threats could Iran pose to ships, exactly?

Just 21 miles wide at its narrowest point, the Strait of Hormuz has long been viewed as a potential chokepoint that Iran could seek to close off during a war.

If the U.S. Navy and its partners try to escort commercial vessels past Iran, "they're 100% going to be shooting at the ships," MacLean said.

The potential threats to shipping traffic currently in Iran's arsenal include naval mines, anti-ship cruise missiles, drones, fast-attack boats operated by Iran's Revolutionary Guards and remote-controlled explosive boats, military and national security experts say. 

Earlier this week, U.S. officials told CBS News that Iran appeared to be signaling it could lay mines in the Strait. The size of Iran's naval mine stockpile is not publicly known, but estimates over the years have ranged from around 2,000 to 6,000.

Top Trump administration officials have said the Strait does not appear to be mined right now. Defense Secretary Pete Hegseth told reporters Friday there is currently no evidence of Iran laying mines, and Bessent pointed out earlier this week that a small number of ships are still traveling through the Strait, suggesting it isn't impassable due to mines.

"The only thing prohibiting transit in the Straits right now is Iran shooting at shipping," Hegseth said Friday. "It is open for transit, should Iran not do that."

Jones told CBS News that Iran doesn't have many large mine-laying ships — and the U.S. military says it has struck about 30 Iranian minelayers over the last two weeks. But Iran does have potentially hundreds of smaller boats that can lay a few mines at a time, and destroying all of them would be extremely difficult, according to Jones.

Some experts caution that Iran could still pose a serious risk to shipping. Michael Eisenstadt, director of the Washington Institute for Near East Policy's military and security studies program, says he's skeptical that an operation to escort oil tankers will work. 

Eisenstadt noted that it isn't clear how many Iranian missiles and drones have survived the last two weeks of U.S. and Israeli strikes, but Iran's remaining stockpiles could be hidden deep in tunnels — meaning Iran could still target ships. He also said that a prior escort operation in the 1980s involved dozens of U.S. vessels, and if the one being considered by the Trump administration is at a similar scale, it could tie up a significant portion of the Navy's fleet.

"All you need is half a dozen drones to hit ships," Eisenstadt told CBS News, "and then tanker owners are going to say 'forget it, thanks guys, nice try.'"

Has it happened before?

This wouldn't be the first time the U.S. has ferried ships through the Strait of Hormuz.

In 1987, near the end of the Iran-Iraq War, the U.S. Navy began escorting Kuwaiti tankers through the Persian Gulf and Strait of Hormuz to protect against Iranian mines and missiles.

"It was a big deal," said MacLean, describing an operation that involved dozens of U.S. ships. 

At one point in 1988, the USS Samuel B. Roberts struck an Iranian mine, causing significant damage and leading then-President Ronald Reagan to launch strikes against Iranian targets. Months later, the U.S. shot down an Iranian passenger plane that it mistook for a fighter jet, killing 290 people in what a U.S. report called a "tragic and regrettable accident."

That war ended with a ceasefire between Iraq and Iran.

If the U.S. decides to carry out another escort operation some 38 years later, MacLean said the mission could end in a similar fashion — either due to a ceasefire or because Iran gives up.

"You basically keep going until there's some kind of inflection point," he said.
